Project 1 - Temperature metric converter
On this page
Learning objectives:
- Create variables
- Use calculations on variables
- Print out helpful message about conversion
Outcomes
We will write a program that can convert temperature data. Your code will automate the process of taking data and making it into a presentable format.
Make a Celsius to Fahrenheit temperature converter
We will write a programme that converts Celsius to Fahrenheit, and Fahrenheit to Celsius. It will then write out a helpful message.
We have two temperatures from a given time in London and New York. The London temperature is in Celsius, and the New York temperature is in Fahrenheit. In the outputs the numbers are rounded to zero decimal places. We are aiming for the following outputs:
The temperature in London is 25ยฐC, which is 77ยฐF
The temperature in New York is 80ยฐF, which is 27ยฐC
Steps to help you get to the outcome
Part 1 - The setup
Open an R script file and save it.
Part 2 - starting with calculations
When working through a problem it is often sensible to break it down and start with something simple.
Use R to calculate:
- 25 Celsius as Fahrenheit
- 80 Fahrenheit as Celsius
Part 3 - using variables
Using the calculations you made, create variables to store the temperature values and the calculated output values.
Part 4 - making a text output
Now we can bring it all together to make our final output.
Use R to make the two text outputs by concatenating elements from one or more variables into a single string.
This should be automated, so if we change the variable for Celsius or Fahrenheit the code will show the new output.
Part 5 - tidy up
Round the outputs to make sure we are looking at whole numbers only.
Part 6 - try different temperatures
Test out your code with different temperatures.
Change your temperature variables to the following:
- 10 Celsius as Fahrenheit
- 20 Fahrenheit as Celsius
Final task - fill out the survey!
